RAYMOND RUSK, DECE-.SED, LATE F SlN ANGELO, TEXAS, BY CLARA. RUSK,ADMINIS- TRATBIX, OF SAN ANGELO, TEXAS, ASSIGNOR 0F ONE-HALF TO JAMES W.LINDSEY,

OF SAN ANGELO, TEXAS.

LIFEBOAT.

Application filed June 18, 1919.

. I, CLARA Rosin, being duly constituted administratrix of the estateor' RaYMoND Rusk, do hereby declare the following to be a full, clear,and exact description of said invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

rllhis invention relates to new and useful improvements in boats, andmore particu` larly to lite boats.

The principal object oi the invention is to provide improved means forpreventing the boat from capsizing.

Another object ot the invention is to provide a skeleton supportingstructure or frame in which a boat is so mounted that the frame mayrotatearound it while the boat floats on the water, said frame beingequipped with means for preventing its sinking.

Another object is to so construct a trame ot this character that theboat may be filled with passengers and rolled ott' the side of a shipwithout the position of the boat being changed and which renders itespecially desirable for use in connection with life boats.

Vith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combi` nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a perspective view of aboat and its supporting structure constructed in accordance with thisinvention, one end of the structure being broken oil for convenience inillustration,

Fig. 2 is a detail longitudinall section through a portion of one of theair tanksl showing the connector which unites it at one end to the boat,and

Fig. 3 is a detail sectional view taken on the line 3-3 of Fig. 1.

Specification of Letters Patent.

Patented Nev. 25, i919.

Serial No. 305,138.

ln the embodiment illustrated, a skeleton body or :trame l is shown ofsubstantially cigar or torpedo shape, in which a boat B is mounted.'This frame is constructed of curved longitudinally disposed laterallyspaced beams 2 composed of any suitable material and converging towardtheir ends. rlhese ends are secured to the centers t of doublecone-shaped air tanks 3, being secured thereto by any suitable means, itbeing understood that one tank is mounted at each end of the frame, theouter cones forming the noses of the frame.

Secured to the beams 2 midway their ends is a ring 5 of channel ironhaving inturned Hanges 6 along its side edges to liorm a housing andguide for a sliding member 7 placed within said ring and to which issecured a plurality of arms 8 which project radially inward betweentlanges 6 and arey secured to the boat B.

The ends of the boat B are swiveled to the inner apices of the air tanks3 by means of 1f-shaped connectors 10, the Shanks 11 of which are roundand rotate in bearings 12 carried by the apices of the tanks. The freeends of Shanks 11 have flat heads 13 which operate to hold the shanksagainst withdrawal from the tanks, while partitions Ba in the tank endsserve as stops to limit their inward movement. The llared arms 14: o'the members 10 are made fla-t and are designed to receive between themthe pointed ends of boat B and to be bolted thereto.

It will thus be seen that the frame 1 may rotate around the boat andprevent the boat from capsizing.

It found necessary a plurality of rings such as those shown at 5 may beused to strengthen the structure, rollers 9 being preferably arrangedbetween member 6 and housing 5 to facilitate the turning of member 5.

By constructing the air tanks in torpedo or cigar shape, the passage ofthe frame or body through the water will be facilitated.

'One or more of the ribs or beams 2 may be made in sections hinged asshown at 15 and connected by a catch 16 to provide for the rapidentrance of passengers to the boat.

From the above description it will be obvious that a boat B mounted asdescribed in the frame 1 will be held at all times in position sol thatthe passengers will remain upright and tilting and rocking of the boatwill be prevented, the frame 1 turning transversely laround the boat andthe air tanks 3, insuring the` iloating of the frame at all` times.

From the foregoing` description, vtaken in connection -with theaccompanying drawf ings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains and whilev l have described theprinciple of operation o' the invention together with the device which lnow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and Ithat suchchanges may be made as are-.within the scope of the claimed invention.

Having thus fully described my inven-l 2. A buoyant supporting frame forboats comprising a substantially cigar-shaped skeleton body, a doublecone-shaped air tank mounted at each end of said body, anv

annular member mounted at the center olf said frame and encircling theboat to be supported thereby, arms .extending 'from said boatand Xedthereto, and a movable member connected to said arms Yand guided by saidLannular member, the ends of the boat having' swiveled connection withthe Vinner apices oi` 'the tanks.

5. A buoyant boat supporting frame comprising' a skeleton cigar-shapedbody having double cone-shaped tanks located one at each end ot saidbody, Y.shaped connectors rotatably mounted in the inner apices of saidtanks and held `against Withdrawal therefrom, the arms of saidconnectors being' designed to straddle the ends of a boat and be Xedlyconnected thereto, and an annular member'fixed to the center of saidframe and encircling' the boat transversely when applied, a. memberslidab-le in said annular member and iixedly connected to the boat whenin use.

ln testimony whereof, I, CLARA RUsK, administratriX of the estate ofRAYMOND RUsK, have hereunto set my hand in the presence of twosubscribing witnesses.
